Some advice from a retired Navy admiral:

In November 1979, when our embassy was sacked and our diplomats were taken hostage, I recommended to the then-acting chairman of the Joint Chiefs of Staff, Adm. Tom Hayward, that our only good option really was to capture Kharg Island, Iran’s principal oil export depot. If we did this, we could negotiate from a position of strength for the immediate return of our embassy and our diplomats.

Unfortunately, the Carter administration rejected any offensive operations as a means of responding to this blatant act of war against the United States. We were humiliated and seemed to the world to lack the courage to defend our honor. Thankfully, we were not faced with a Falklands Island situation because we did not have a Margaret Thatcher but surely needed one.

Still seems like a good idea.
